The Implications of N = 2 Supergravity Cosmology On the Topology of the Calabi-Yau Manifold
Safinaz Salem, Moataz H. Emam, H. H. Salah
When N= D=11 supergravity is compactified on CY threefold to N=2 D=5 supergravity the action of the last is given in terms of the geometery of the CY manifold space, namely, in ter…
